چکیده

The asymmetric unit of the title compound, C(20)H(24)N(2)O(6), contains one half-mol-ecule, the complete mol-ecule being generated by a crystallographic inversion centre. The mol-ecule is nearly planar with a dihedral angle between the two benzene rings of 0.03 (4)° and the central C/N/N/C plane making a dihedral angle of 8.59 (7)° with each of its two adjacent benzene rings. The two meth-oxy groups at the ortho and meta positions are slightly twisted [C-O-C-C torsion angles = 7.23 (12) and 5.73 (13)°], whereas the meth-oxy group at the para position is almost coplanar with the attached benzene ring [C-O-C-C torsion angle = -2.02 (13)°]. The crystal structure is stabilized by a weak C-H⋯π inter-action.

The title mol-ecule, C(20)H(24)N(2)O(6), lies on an inversion centre. All non-H atoms are essentially coplanar, with an r.m.s. deviation of 0.0415 (1) Å and a maximum deviation of 0.1476 (1) Å for the meth-oxy C atom at the 4-position of the benzene ring. The crystal structure is stabilized by weak C-H⋯N and C-H⋯π inter-actions.

Synthesis and anticancer evaluation of novel acenaphtho [1,2-e]-1,2,4- triazine derivatives

In this paper we present the convenient syntheses of seven new phenyl hydrazin derivatives 8 (a-h). For this purpose, acenaphtho [1,2-e]-1,2,4-triazine-9(8H)-thione (3) was prepared, starting from acenaphthylene-1, 2-dione (1) and thiosemicabazide in good yield. The reaction of (3) with benzyl chloride resulted to synthesis of 9-(benzylthio)-acenaphtho[1,2-e]-1,2,4-triazines (5) that reacted wi...
